Are mums annuals or perennials?

Garden mums are tender perennials that last longer than a year, depending on when and where they are planted, according to Briggs Garden and Home. Mums are a great choice to put fall color in the garden.

Mums should always be planted in the spring or summer so that the plants have the ability to establish a good root system, according to Briggs Garden and Home. A moist and warm ground allows the mums to overwinter and to live to the next season. Pinching back a mum encourages it to branch out and create a more compact shape and size.
